100% Polyester Fleece Base Layer

Simms’ Guide Core Top delivers plush next-to-skin comfort as part of a dynamic layering system. For arctic days, lightweight fleece in an abrasion-resistant knit delivers anti-pilling performance for long-term durability and warmth under waders. The 9-inch zipper makes slipping in and out a breeze and allows you to dump—or hold—heat when the fishing fires up.
